2 Claims.

The invention relates to incinerators and particularly to that type of incinerator wherein the garbage or material to be consumed acts as the fuel.

The principal object of the present invention is to provide a means for equally distributing air through and over the mass of material to be consumed thus insuring complete combustion and thorough drying.

With the foregoing and numerous other objects in view which will become apparent as this specification proceeds, the invention resides in the combinations and arrangements oi parts which are shown in the accompanying drawings illustrating a preferred embodiment of said invention.

Referring to said drawings:

Fig. l is a vertical sectional view through the incnerator and part of the flue, one of the doors leading to the fiue being shown in elevation.

Fig. 2 is a fragmentary detail perspective view illustrating the method of setting up the brick work in the incinerator Walls.

Fig. 3 is a horizontal sectional view taken on the line 3-3 of Fig. 4.

Fig. i is a front elevation.

The incinerator, particularly illustrated in Figs. 1, 3 and i comprises iront and rear walls and 11, side walls 12 and 13, and a roof 14. The walls and roof enclose a combustion chamber and an ash pit 16 between which are any suitable form of grates indicated at 17. A flue 18 enters the roof of the incinerator, the flue forming an outlet for the products of combustion and an inlet through which refuse or other material may be fed into the incinerator.

The iiue up to a certain height and the walls of the incinerator are lined with a refractory material 19. This refractory material is preferably re brick and as shown in Fig. 1 it need not extend below the grates 17.`

`Air passages 20 and 21 are provided between the side walls 12 and 13 and the refractory liningr and an air passage 22 is formed between the rear wall 11 and the refractory lining. The air passages 20, 21 and 22 communicate with each other and thus form a common air passage extending about the three sides of the furnace. The air passages are preferably narrow in width and are not to be considered as air chambers such as are used in some prior art devices. The lower parts or said air passages are substantially in line with upper part of the ash pit and they extend upwardly to the general region of the roof.

Outside air is supplied to the air passages (c1. 11o-s) through channels 23 leading out of the lower part of the front wall of the incinerator. The amount of air entering the passages may be controlled or regulated by dampers 24 of any appropriate construction.

The iront wall 10 is provided with fire-doors 25 which have the usual means for controlling admission of air. The conventional ash doors 26 are also located in the front wall.

The outside air passes from the air passages 20, 21 and 22 into the combustion chamber 15 through ports 27. These ports 27 are provided on the three sides of the incinerator. By this arrangement an equal air distribution is provided throughout the entire combustion chamber thus insuring complete combustion and a` thorough drying of the material to be consumed. Applicant is aware that numerous methods have been devised and are in use for providing additional air for the combustion chambers of incinerators but he believes it to be new with him to form air passages on three sides of the incinerator with ports leading from said air passages to the combuston chamber and outside air supplied to the air passages through regulated openings.

Particular attention is now drawn to the construction of the refractory lining and the ports. The outside walls of the incinerator are built of common red brick or other solid masonry construction. The refractory lining as heretofore stated is formed of fire brick. Due to the fact of fire brick not having a great amount of strength, particularly when built into a wall by itself, it is desirable to provide a means to support it.

For this purpose headers 28 are supplied, the headers being firmly mounted in the solid brick walls and extending across the air passages and into the refractory lining. The headers are conveniently formed of one conventional re brick laid in its course at right angles to the other bricks in the course as particularly shown in Fig. 2. The openings left on either side of the headers provide the ports 27. The inner faces of the headers are set back from the inner surfaces of the refractcry lining. By virtue of this construction if a gob of material is lodged against the lining in the region of one of the sets of ports and does not entirely cover the rectangular opening the air will pass around the recessed or set back part of the header and still maintain the equal air distribution. Other air spaces 29 may be vprovided between the refractory lining and the walls and roof for insulating purposes.

At different points in the lflue 18 preferably at the floor levels, openings are provided through which the refuse or material to be fed into the incinerator may be dumped.

Such changes in arrangements of parts and details of construction as would occur to one skilled in the art are to be construed as coming Within the scope of the invention as expressed in the appended claims.

I claim:

1. An incinerator comprising walls and a roof, a iiue through which material may be fed into said incinerator and products of combustion may escape from said incinerator, a refractory lining for said incinerator spaced from said walls to form air passages between said refractory lining and the Walls, the bottom of said air passages being substantially in line With the upper part of the ash pit of said incinerator and said air passages extending substantially to the roof of said incinerator, headers extending between said refractory lining and said Walls, the inner ends of said headers being set back from 'the inner surface ofv said refractory lining, ports adjacent said headers and leading from said air passages to the combustion chamber of said incinerator, and regulated means for admitting outside air into said air passages.

2. An incinerator comprising Walls and a roof, a iiue through which material may be fed into said incinerator and products of combustion may escape from said incinerator, a refractory lining for said incinerator spaced from said Walls to form air passages between said refractory lining and the Walls, the bottom of said air passages being substantially in line With the upper part of the ash pit of said incinerator and said air passages extending substantially to the rooi of said incinerator, headers extending between said refractory lining and said Walls, the inner ends of said headers being set back from the inner surface of said refractory lining, ports on both sides of said headers, said ports leading from said air passages to the combustion chamber of said incinerator, and regulatedmeans for admitting outside air into said air passages.
